Am I overreacting because my husband just asked was I on my period

This morning I got a call from the police because my son was skateboarding by his school and some boys held him at gun point to take his shoes and then beat him. I of course ran to the police station and we decided to get him checked out at the hospital and he's gonna be okay but he's just a little messed up. I called my husband a million times at work but he never answered. When he got home I told him and he said "Oh". Just oh. I asked was that it. Our son was held at gun point and beaten up and he had the audacity to say "Is he dead?" I said obviously not but this is serious! And he said I'M overreacting and then he says "Are you on your period or something?" He makes me so angry that I screamed at the top of my lungs and walked out and kicked the laundry basket and went outside to hit my punching bag. My son came with an ice pack on his face asking am I okay and I said yes ajd asked if hes okay and he said "I'm still seeing doubles but I'm okay." And my husband just does not care. He is such a fucking idiotic asshat!

Edit: He's not great father or husband. He's extremely selfish and immature. He's the reason our neighbors hate us. He's banned from our son's school because he can't behave himself. He's always doing the dumbest shit to the point I HAVE to get a punching bag to deal with him. He made our son drive him home drunk when he was 12! He's irritating and the very LEAST he can do is show some fucking concern for our God damn child!
